I can really appreciate the amount of work you put into making this piece! I also like how this has that tattoo look. There are a few things you can do to make your car drawings better. When it comes to drawing cars (and many other things, but especially cars), proportions are important. That means that you need to get the sizes and shapes of the features to be 80-100% correct for it to look like the car you're trying to draw. Another important thing is perspective. Right now your front and rear wheels are more or less the same size. Which makes the car look like a small toy and the viewer is very closed up. It just takes practice and a little bit of studying!But technical details aside, I still like how this looks. I can tell how patient you are by the way you rendered everything smoothly. Keep it up!!
